HINGE.

Application med August 25, 192e. seriai No. 131,415.:

This `invention relates to cas-ement Window hinges, and more especially-to a device which attachable to the Wings'n or leave-sof such hinges for the purpose of frictionallyvbut firmly'securing the swingingwindow at any A the unit applied thereto. 4

desiredangle :Within its limit of movement. An object is to` providea friction unit i read-ily, applicableto such type of hinges withv little or no change. in the constructionthereofi Anotheraobject is to provide 'a friction unit with means yto apply'readily on thev usual leavesfsothat the swinging leaf may have theusualfmovementand will rest firmly A further object is ito3provide a friction unit Vso interlockablewvith the hinge that the unit vcan be removed only, but easily, at one position.f of theV hingeleaves.. l

A still further object is to pr-ovide a friction unit includingfafhinge pintle substitutable :fori the usual lhinge pin and having friction members engaging, immovably, relative .stockleavesdof the hinge Without in any .Way altering the,l leaves, so thatk the present holdinff unitmay `loe-applied to stockl or to installediinges ofstanda-rdtype With removing Vhung out discarding Astock or hinges.

The invention vis notlimitedin itsV objects to those above; enumerated, andothe'r pur.-

poses, features andadvantages lWill be made manifest, in= the `following specification of the embodiments illustratedtherewithg it be-` ing reserved'a-ndunderstood that modifications, variations and adaptations may be resorted to within the spirit and principle of the invention as it is` here claimed.

The companionl leaf B hasv itsjournal-'bm4 cut down from the top and ata pointjnstgxy pposite the'hornal it has an anglerecess stock leaves of such hinges, which usually.- have a removable pivot pin.l

The interlocking friction unit a `pintle 3 with asmallvshoulder 4 andv av screw-threadedend"5 on which is tur-liable' a clampnut 6 havinga cross-slot 7 fora 'screw-driver or yother suitable implen'ient.v

This is the only difference from the comprises2 Preferably thevhead of the screw end 5 is i burred over soas to beingl run offf A y Fixed on Atheypintle and setting against prevent the nut "from the shoulder 4iis a lovver friction plate A1'() joined by a tieor loop 11 to'an upper 'plates y.

12. These .plates are.` spaced axiallyl to re`V ceivea turnable, intermediatee friction disk 14. The lower plate 10 hasy a notch 10a, slightly tangential to its axis, to receive the corner b2 ofthe leaf B so that the plates 10-12 are engaged to the leaf B against relative movement.- The recess b1 just clears the edge of the middle disk 14, Which has a notch 14a to receive the horn a1 of the leaf to interconnect these parts. i

The plates 10-12 and the disk 14 have rim-marks 16, Fig. 1, and When these are in alinement notch 14a, of disk 14, registers i over a clearance slot 10b 10. lVhen in such relation the friction unit is dropped into place on the top of the properly angled leaves A-B .(Fig. 2) leaf B passing into notch 10a and horn a1 passing in the edge of plate up into notch 14a, and pintle 3 fitting into the leaf journals.

Vh'en so assembled, ifthe leaves are now opened out the disk 14 turns andthe horn a1 passes away froin the clearance slot 10b, which results in interlocking the unit Vin place so that it cannot be pulledl axially from the hinge, which, obviously, is an ini-.

portant advantage. Another advantage is that the friction adjusting nut 6 cannot be run off the unit and lost.

One or more of the friction hinges may be used in hanging a window, or other swinging structure, and by means of the nut 6 the frictional resistance kagainst movement of the swinging pai-t may he easily regui lated.' It will be noted that no loosening a side shoulder 21a below'the plate 20 and to engage the side of leaf B as seen in Fig.

10. Adjacent to the shoulder 21a there is a .tangentialr kerf 21" and a tongue 21'3 is to engage'against the near face of the leaf B, which is, therefore, retained between shoulder 21a and tongue 21C. This holds the leaf B as to the pintle Turnable between the lplates 20-22is'a disk 24, on the pintle 3, having a lateral, down-turned yoke 24a the slot 24b of. which y is tangential to the aXis of the disk.

The unit is aposition shown in Fig. 8.

t rilhe pintle 8 is secured in place by application of nut 6 to its lower end. When the plates and the disk have been hooked onto the leaves A-B the nut is tightened up as desired and so obtain plate friction onthe disk1 t0 hold the swinging leaf at the desired ang` e.

The advantage of this form of hinge clamp is that it can be applied without alterj ing the hinge leaves in any manner.
